American flight attendant revealed the sound of the aircraft landing signal 
American Airlines employee Tommy Cimato, who became famous on social networks videos about the profession, revealed facts about his work that were unexpected for passengers. He shared them on his personal TikTok account.
Chimato explained that when a passenger presses the call button for the flight attendant, a green light comes on not only above his seat, but also in the aisle of the plane not far from his row. Thus, the crew members can quickly navigate and understand in which part of the plane their help was needed.
In addition, the American revealed the meaning of the double beep, which sounds like a flight attendant call in tone. According to him, in this way the aircraft commander warns the crew about the last decrease in altitude and an imminent landing (within about ten minutes).
Earlier in November, the same employee of the American airline explained the secret meaning of sound signals for crew members at board the aircraft. According to him, two signals (the first in high pitch, the second in low) during the flight mean an incoming phone call at the flight counter or when a flight attendant from one part of the liner tries to contact a colleague who is in another sector of the aircraft.
